"They're incredible and the best thing is that they have this washable cloth sleeve (pre filter) that goes over the entire intake which happens to wrap all the way around. ... It does such a good job that the actual internal filter stays significantly cleaner and doesn't need to be cleaned or changed as often. ... It's a game changer."
"Blueair imo because they have washable prefilters, and pet hair and dander is large and honestly doesn't need HEPA filters to clear it out the way, say, smoke does."
"The outer pre-filters do put up a lot of dust and I can throw them in the wash."

"I don’t like they have an ionizer that you can’t disable. ... Ionizers create ozone, and when ozone reacts with different molecules it creates all kinds of new compounds that can’t be predicted."

"OTOH, the two Blueair purifiers are on all the time and we have ***not*** noticed a decrease in the rate at which dust accumulates on the woodwork in the house."

I love my Blueair. It’s either a 500 or 600 model and I usually get the smoke filters because they have carbon in them and it helps with pet odors. I really like it.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I have one and think it is worth $50. I got it at Blueair and it was on sale for $300 or so off. It's a very expensive air purifier and three filters are need. If you want odor control, too, you must get the [Classic 500/600 Series DualProtection Filter](https://www.blueair.com/products/500-600-series-dualprotection), as opposed to the filters that just clean the room. They range from $120-150 for three, depending on where you buy them online. The Blueair website even has a subscription plan where you get a discount for subscribing. I'm using it in a foyer which is connected to a living room and dining room, and it works fine. The foyer is right off the breakfast nook and kitchen, and it does an excellent job eliminating cooking smells that drift into the foyer and can travel upstairs. The first two speeds are quiet, but the third highest speed is very, very loud. I also have the Blueair 211+ and 211 Auto in other rooms and really like them, too. If I need air purifiers in the future, I will always buy Blueair.
r/AirPurifiers • Found a blue air Classic 500/600 ->Used purifiers can be a good deal, but a new filter for this model is well over $100 so your cost of ownership is going to be expensive going forward. Need to make sure you’re ok with those costs BlueAir has almost exclusively switched to circular filters, so there’s always a chance they will stop producing replacement filters for this model at some point. Also, purifiers are not designed to eliminate odors even though they market them that way. They can help, but it’s not going to make a huge difference. Also you have a very large space at 800sq ft, so you will most likely need multiple units to properly clean your air
r/AirPurifiers • Found a blue air Classic 500/600 ->In practice they all work fine, usually getting more units is better than getting a higher end one. In my opinion: The best air filters are installed into a new air system such as Daikin, that allows net positive pressure to be inside as it pulls filtered air outside, preventing a leaky home from pollutants entering. But given it needs to pull outside air to get positive pressure inside, it can bring other pollutants unless you get the more expensive charcoal based filters. Most folks don’t have this unless they remodel their homes or it came with it. The second best I prefer is the largest blue air with their charcoal based smoke stop filter that can help clean up VOCs. They have good airflow with low sound, and their filters are quite effective at removing pollutants.
r/chinalife • Let's settle this - What's the very best air purifier you can buy in China? (no budget limit) ->I have a giant blue air and I love it. Before we didn't have one in a smaller space and I feel some days I was dying. The cost of the filters is kind of pricy though.
r/CatAdvice • Best air purifier for a studio apartment? ->Coway and BlueAir are great. Make sure it says "True HEPA," unless you build a corsi-rosenthal box Levoit ones aren't always true hepa.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->We run 3 in our house, one in the main living area (diy pc fan with hvac filters), and one in each bedroom (blue air brand or something, I think). Also consider plastic on leaky windows (cheap sliders).
r/saskatoon • Air purifier ->I have a few Levoit the same size as this one. I don’t really care for them compared to the Winix and Blue Air ones I have.
r/AirPurifiers • Is this worth the money ? ->Love mine too. We got 3 and they’re holding up better than the Blue Air’s I got.
r/HomeKit • Best HomeKit air purifier? ->I have terrible allergies and use Blue Air on every level. Works amazing.
